Novel germline MLH1 and MSH2 mutations in Latvian Lynch syndrome families.

Three novel germline mutations in MLH1 and MSH2 in families with Lynch syndrome living on Jeju island, Korea.

Hereditary non-polyposis colorectal cancer (HNPCC) is an autosomal dominant syndrome characterized by predisposition to early-onset cancers. HNPCC is caused by heterozygous loss-of-function mutations within the mismatch repair genes MLH1, MSH2, MSH6, PMS1, and PMS2. We genotyped the MLH1 and MSH2 genes in patients suffering from Lynch syndrome and in 11 unrelated patients who were diagnosed wit...

سه موتاسیون ژرم لاین جدید در ژن MLH1 در بیماران مبتلا به سرطان کولورکتال ارثی

Abstract Background: Hereditary non-polyposis colorectal cancer is the most common cause of early onset of hereditary colorectal cancer. In the majority of Hereditary non-polyposis colorectal cancer families, microsatellite instability and germline mutation in one of the DNA mismatch repair genes in clouding MSH2, MLH1, MSH6 and PMS2 are found. The Objective of this study was to determine th...

Mutation screening of MSH2 and MLH1 mRNA in hereditary non-polyposis colon cancer syndrome.

Germline mutations in four human mismatch repair genes (MSH2, MLH1, PMS1, and PMS2) have been reported to cause hereditary non-polyposis colon cancer syndrome (HNPCC). The identification of germline mutations in HNPCC kindreds allows precise diagnosis and accurate predictive testing. To investigate further the genetic epidemiology of HNPCC and the nature and frequency of germline mutations in t...

The Mutational Spectrum of Lynch Syndrome in Cyprus

Lynch syndrome is the most common form of hereditary colorectal cancer and is caused by germline mutations in the mismatch repair (MMR) genes MLH1, MSH2, MSH6 and PMS2. Mutation carriers have an increased lifetime risk of developing colorectal cancer as well as other extracolonic tumours. The aim of the current study was to evaluate the frequency and distribution of mutations in the MLH1, MSH2 ...
